Whew...that's some top-quality bullsh*ttin', right there. If that's critical thinking, what is un- or "noncrtical" thinking? Instinct? Seriously people, think for a minute, critically or otherwise. Maybe it means this. Or just about whatever you want, because like most edubabble, it means "I sure wish I could make this sound smart even though it isn't." (Sort of like "rectifying a consequence for a tardy", which I think in olden days was just called "getting detention". Note: How does one "rectify a consequence"?)

"In math, the shift is away from lectures and rote working of equations
to the practical application of mathematical processes, often in teams,
to real-world situations."

Showing how they're used in real-life is great--except you have to pick a few examples of how it is used, since you can't possibly cover every one. Which means you're still not really "getting it". Sure, toss in some examples, but the key is that the kids can actually do the work. That way, if they are asked to apply it professionally later in their lives, they can. Practice, practice, practice!

"The idea is to help students gain "a broader understanding of mathematical purpose..."

Again, that's all well and good, but it's more important that they can actually DO the math, isn't it?

"Students will study only the immune, endocrine, and nervous systems rather than all 11 body systems."

And here we have the real crux of the problem: High School should be getting as broad an education as possible, in my opinion. College, whether it be community, undergraduate university, or the ultimate in specialization, graduate school, can provide the details once the student has chosen a career path.
